28fd93073a libfetch: Avoid SIGPIPE on network connections.
To avoid unexpected process termination from SIGPIPE when writing to a
closed network connection, enable SO_NOSIGPIPE on all network connections.

The POSIX standard MSG_NOSIGNAL is not used since it requires modifying all
send calls to add this flag. This is particularly nasty for SSL connections.

30787285b5 Since the socket is non-blocking, it is necessary to use select(2) even
when there is no timeout, because read(2) will return immediately if there
is no data waiting in the TCP buffer, causing fetch_read() to busy-loop on
slow connections.

0fa391997a Support percent-encoded user and password
RFC 1738 specifies that any ":", "@", or "/" within a user name or
password in a URL is percent-encoded, to avoid ambiguity with the use
of those characters as URL component separators.

2a7daafe67 Fix two issues related to the use of SIGINFO in fetch(1) to display
progress information.  The first is that fetch_read() (used in the HTTP
code but not the FTP code) can enter an infinite loop if it has previously
been interrupted by a signal.  The second is that when it is interrupted,
fetch_read() will discard any data it may have read up to that point.
Luckily, both bugs are extremely timing-sensitive and therefore difficult
to trigger.

caaffed8f0 Redo fetch_read() using non-blocking sockets. This is necessary to
avoid a hang in the SSL case if the server sends a close notification
before we are done reading.  In the non-SSL case, it can provide a
minor (but probably not noticeable) performance improvement for small
transfers.

962cf29525 If the A flag is supplied, http_request() will attempt the request only
once, even if authentication is required, instead of retrying with the
proper credentials.  Fix this by bumping the countdown if the origin or
proxy server requests authentication so that the initial unauthenticated
request does not count as an attempt.
